LAUSR

The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a spectrum of anomalies arising from incomplete development of the Müllerian ducts, is characterised by congenital aplasia of the uterus and upper part of the vagina, often in the absence of other phenotypical abnormalities. We report the case of a 13-year-old girl referred to our endocrinology unit after an incidental finding of uterine agenesis during laparoscopy to correct suspected ovarian torsion. Initial transabdominal ultrasonography found no uterus. Given her normal secondary sex characteristics, karyotype and hormone profile, MRKH syndrome was initially diagnosed. However, after vaginal bleeding compatible with menstruation, repeat transabdominal ultrasonography and MRI revealed a left-deviated unicornuate uterus.
